+ * o  revision: Each YANG module and submodule within the library has a

+ * exists, the module's or submodule's revision is the zero-length
+ * string.
+ *
+ * o  submodule list: The name and revision of each submodule used by
+ * the module MUST be identified.
+ *
+ * o  feature list: The name of each YANG feature supported by the
+ * server MUST be identified.
+ *
+ * o  deviation list: The name of each YANG module used for deviation
+ * statements MUST be identified.
